Abstract
The fine structures of the oxygen K-edge in the Tl1Ba2Can-1CunO2n+3 with single Tl-O layers were investigated by electron energy loss spectroscopy (EELS). The peak corresponding to the hole state near the Fermi energy was sensitive to the number of Cu-O layers and the direction of momentum excitation. It was shown that the hole content in Tl1Ba2Can-1CunO2n+3 decreases with the increase of n (n=2−4) and that most holes exist in the O 2px, y orbitals of 2-dimensional Cu-O planes.
